Install processing apparatus, processing method, storage medium, and program

Abstract

An object of this invention is to prevent installation of an unnecessary application into an embedded device. To achieve this object, a control program according to this invention includes a module (208) which stores system information of an embedded device (101), a module (205) which loads an application (201), an module (206) which determines on the basis of a loaded execution module (203) and the system information whether the application (201) normally operates, a module (209) which determines on the basis of a property (202) and the system information whether the application (201) normally operates, and a module (210) which outputs an error when the application is determined not to operate normally.

Description

FIELD OF THE INVENTION [0001] The present invention relates to a processing technique used to dynamically install an application into an embedded device. BACKGROUND OF THE INVENTION [0002] Of various digital devices ranging from office equipment such as a copying machine and facsimile device to a portable terminal and interactive television, Non-PC devices except a so-called personal computer are generally called embedded devices. [0003] Conventionally, an application in such an embedded device is statically linked to compilation and installed in the system when the system is constructed. It is often impossible to dynamically install an application during the operation of the embedded device. However, as many embedded devices are equipped with an Internet connection function, an application is installed into an embedded device from a Web browser in a PC (Personal computer) or WS (Work Station), or an embedded device itself downloads a necessary application from the Internet or a fil...

Benefits of technology

The present invention aims to prevent unnecessary applications from being installed and executed in embedded devices. To achieve this, an install processing method is provided that includes steps of analyzing the content and property of an application, and notifying the user if the application does not operate normally. This method helps to improve the efficiency and accuracy of installing applications on embedded devices.

Problems solved by technology

It is often impossible to dynamically install an application during the operation of the embedded device.

In the prior art, even if the OS or version is proper, the operation of an installed application is not always guaranteed depending on a device support situation such as a hardware resource including a memory capacity or storage device capacity, or a network connection function.

This problem is serious particularly in an embedded device.

This is because the hardware resource is minimized for low cost, and another application may fail due to a shortage of the memory capacity or storage device capacity.

If tasks exceed the limit value of tasks usable in the system, the original function of the embedded device may fail, and in the worst case the system may fail.

The same problem also occurs when a Java application or Java applet is installed into an embedded device having a Java execution environment.

Even if a Java application requires a Java class library created by the user or a Java class library unique to the device, whether the Java application normally operates cannot be known until it is actually installed and executed.
